Hi,
Firstly the dmesg command should allow you to see the
boot time messages which might let you see the mount
errors
Secondly mount and df seem to get confused when the
fstab file doesn't tie up with reality
Try:
sudo vol_id -u /dev/hda1
which gives the UUID for your root filesystem device.
If things are set up right it should return:
a3de38df-11f4-4598-bb06-adc801711814
But if not your /etc/fstab file is messed up and you
need to change the:
UUID=a3de38df-11f4-4598-bb06-adc801711814 / ext3
defaults,errors=remount-ro 0 1
line to have UUID=[whatever vol_id returned]
Alternativly change it to:
/dev/hda1 / ext3 defaults,errors=remount-ro 0 1
which is less Ubuntu-esque but more unixy and will
work.

Running sudo mount -av gives me:mount: proc already

I see what appears to be the mount help displayed as
if mount has been run with an invalid argument but I
am unable to find this in a log file anywhere to
check.Probably unrelated but I am booting with the
irqpoll option.Any suggestions on how to troubleshoot
this would be appreciated!I've also lodged with as a
support request at
